Updating ssis packages Dating grannies sex
A task is an atomic work unit that performs some action.
There are a couple of dozen tasks that ship in the box, ranging from the file system task (that can copy or move files) to the data transformation task.
It features a data warehousing tool used for data extraction, transformation, and loading (ETL).
The tool may also be used to automate maintenance of SQL Server databases and updates to multidimensional cube data.
A workflow can be designed for a number of events in the different scopes where they might occur.
In this way, tasks may be executed in response to happenings within the package — such as cleaning up after errors.
A scripting environment in which to write programming code is also available in the tool.
Before running the package, the tool may be instructed to apply configuration information, which will allow the same package to be reused with slightly different parameters, including different connection strings for its endpoints.
Constraints may otherwise allow different paths of execution depending on the success or failure of other tasks.
Together with the tasks, precedence constraints comprise the workflow of the package.
A connection includes the information necessary to connect to a particular data source.
Tasks can reference the connection by its name, allowing the details of the connection to be changed or configured at run time.
